SYNOPSIS
Moderate easterly trades will continue through the first half of the week, with clouds and light showers favoring windward and mauka locations during the nights and mornings. A return of breezy easterly trades and increasing rainfall chances is possible for the second half of the week, as an upper disturbance moves into the area.
DISCUSSION
Guidance remains in good agreement, indicating dry and stable conditions continuing through the first half of the week as upper heights rise over the region. This will create a more suppressed environment with precipitable water values remaining around an inch or less and a strong subsidence inversion hovering around 5-6 kft. The best chances for a few, mostly light, showers will be over typical windward and mauka locations overnight through the early mornings with moderate easterly trades continuing. Any leeward showers are more likely to occur in the afternoons, where localized sea breezes form. Accumulations will be minimal with the stable conditions in place.
A gradual strengthening and destabilization of the trade wind flow is possible through the second half of the week. There is higher confidence that trades will likely increase as a deeper surface high sets up far north of the state, potentially resulting in breezy conditions by Friday. An upper-level trough will slowly pass over the region during this time, bringing 500 mb temperatures as low as -15C Wednesday through Friday. While there could be some increase in shower coverage in response to the added instability, a mid-level ridge may be able to maintain stability and lower the chances of locally heavy rainfall.
Guidance shows a pulse of upper-level energy dipping southward on the backside of this upper trough Friday through Saturday, potentially closing off an upper low over the eastern end of the state. If this were to materialize, these conditions anticipated through the second half of the week could linger through next weekend.
AVIATION
Moderate easterly trades will persist, with clouds and showers favoring windward and mauka overnight through the morning hours.
Outside of a brief shower moving through leading to MVFR CIGS/SHRA, VFR conditions will prevail.
MARINE
Trades have eased back to more moderate magnitudes as a result of high pressure settling in north of the coastal waters. Little change is expected through Wednesday when another high develops farther north of the region. This high will build in Thursday and Friday and tighten the regional pressure gradient enough to strengthen trades back to fresh to locally strong levels into the weekend.
A few overlapping northwest swells are scheduled to arrive this week. The latest moderate size, long period northwest (310-320 degree) swell peaked surf to near or slightly under High Surf Advisory (HSA) thresholds along most north and west-facing Kauai- to-Maui shores early this morning. This swell has decline through the afternoon and into Tuesday to then be followed by a slightly larger northwest (310-330 degree) swell building in Tuesday night.
As a result, the arrival of this high end moderate size, long period swell will likely produce mid week advisory level north and west-facing shore surf. North and west shore surf will fall below HSA heights Thursday. A moderate size northwest (310 degree)
swell is due next weekend. A weak pulse of early season, south southwest (200 degree) swell has been passing through the past day or so. Expect this inconsistent swell to peak south-facing shore surf at slightly above March averages through tonight, then surf will gradually decline with the fading swell through Wednesday.
East shore surf will remain small through the middle of the week.
There will be a slight pick up in chop later this week in response to strengthened trades.
